5 Formation

5.1 Formation

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Lignite vs Anthracite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Lignite and Anthracite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Lignite vs Anthracite information and Lignite vs Anthracite characteristics in the upcoming sections.

More about Lignite and Anthracite

Here you can know more about Lignite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Anthracite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Lignite is Veined or Pebbled and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Lignite vs Anthracite. The hardness of Lignite is 1 and that of Anthracite is 1-1.5. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lignite and Anthracite is black. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Anthracite is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Lignite is heat resistant whereas Anthracite is heat resistant, water resistant.
